The protein encoded by SSB（Sjogren syndrome antigen B） is involved in diverse aspects of RNA metabolism, including binding and protecting poly(U) termini of nascent RNA polymerase III transcripts from exonuclease digestion, processing 5' and 3' ends of pre-tRNA precursors, acting as an RNA chaperone, and binding viral RNAs associated with hepatitis C virus. Autoantibodies reacting with this protein are found in the sera of patients with Sjogren syndrome and systemic lupus erythematosus. Alternative promoter usage results in two different transcript variants which encode the same protein.蛋白別名為：SSB; Lupus La protein; La autoantigen; La ribonucleoprotein; Sjoegren syndrome type B antigen; SS-B;基因ID為：6741；蛋白質ID:P05455
應用類型
WB，IHC-p，IF，ELISA補充：最優的抗體稀釋比例需要基于客戶實驗進行優化.建議的起始稀釋比例如下: WB: 1:500-1:2000, IHC-p: 1:100-1:300, IF: 1:200-1:1000, ELISA: 1:40000. Not yet tested in other applications.
